Question

If
Seco + tano = 2, then what is the value
& Seco-tano​

Answer 1

Step-by-step explanation:

If. sec theta + tan theta = 2 then,

$( {sec)}^{2} theta - ( {tan)}^{2} theta = 1$

$(sec \: theta \: + tan \: theta)(sec \: theta \: - tan \: theta) = 1$

$2 \times (sec \: theta \: - tan \: theta) = 1$

$(sec \: theta \: - tan \: theta) = \frac{1}{2}$

The value of (sec theta - tan theta) is 1/2.
